VulkanRipper 1.9 brings possibility to get projection matrix candidates for most Vulkan/DirectX games analyzing meshes.
After performing the "Projection Pass" menu, a dialog box will appear containing candidates for the inverse projection matrix, indicating their validity, accuracy, aspect ratio, and field of view. Select one of the valid matrices from the list and click "Install Selected". This matrix will now be applied to the meshes until you change it.
The matrices are also recorded in the log file. You can find them by "ProjectionMatrix" tag.
